context_page_description: Pre-Pottery Neolithic B is part of the Pre-Pottery Neolithic, a Neolithic culture centered in upper Mesopotamia, dating to c. 10,800 – c. 8,500 years ago, that is, 8,800–6,500 BCE. It was typed by Kathleen Kenyon during her archaeological excavations at Jericho in the West Bank. Like the earlier PPNA people, the PPNB culture developed from the Mesolithic Natufian culture. However, it shows evidence of a northerly origin, possibly indicating an influx from the region of northeastern Anatolia.
context_section_description: The spread of the Neolithic in Europe was first studied quantitatively in the 1970s, when a sufficient number of 14C age determinations for early Neolithic sites had become available. Ammerman and Cavalli-Sforza discovered a linear relationship between the age of an Early Neolithic site and its distance from the conventional source in the Near East (Jericho), thus demonstrating that, on average, the Neolithic spread at a constant speed of about 1 km/yr. More recent studies confirm these results and yield the speed of 0.6–1.3 km/yr at 95% confidence level.
